SL4540 Gen8 backup/clone problem

CMU version 7.2

Backup/Clone target:

SL4540 Gen8 running RHEL 6.4 x86_64

BIOS: 2/10/2014

B120i: 4.50

iLO: 1.50

When trying to backup one of the SL nodes, the system successfully reboots, pxe boots, and then goes into an endless loop of various Call Trace outputs and USB disconnect/uhci_hcd events (see attached screenshot)

The backup job eventually times out and fails, but the SL node continues in this endless loop

I have blacklisted ahci as suggested in the user guide for the B120i controller.

I have also blacklisted hpsa to prevent the P420i controller from loading

When kicking off the backup job, I select sda partition 3...this is where the / partition resides
